Protecting sensitive data (credit card numbers) in email messages
iQ.Suite Tips & Tricks for IBM Domino
Version 14 of iQ.Suite (Wall module) for Domino checks whether an email contains credit card numbers.
Because emails transmitted over the Internet in SMTP format are usually unencrypted, this involves a certain level of risk.
This calls for a “Wall advanced” job.
You can simply copy the job provided here as an example and adapt it to your requirements.
To perform the analysis you must select the appropriate mode, utilities (blue), and the Credit Card Number Analyser tool (red).
Then select the elements of the email you want to analyze (green).
For the threshold values we have selected two options:
1.) ONE credit card number was recognized with certainty
2.) THREE numbers were detected that are probably credit card numbers
If one of these two options is true, then this email is processed in accordance with your chosen actions (e.g. do not deliver email but send to quarantine, where it is checked and may then be delivered).
Message to sender:
Extract from quarantine report:
The analyzer recognizes which credit card company issued the number from a particular combination of digits in the number.
In the interests of data protection, only the last digits of the credit card number are shown in the report.
